Faxon Firearms Sig P365 Barrel Features The Faxon Firearms Duty barrel is a drop-in replacement built from stress-relieved 4150 CMV steel chambered in 9mm Luger and machined specifically to fit the Sig Sauer P365. A full black nitride finish covers the barrel inside and out delivering maximum corrosion resistance wear protection and lubricity for the bore and exterior alike. The 1:10 twist rate stabilizes standard 9mm loads reliably keeping accuracy consistent across a range of factory ammunition. Conventional button rifling gives the barrel a smooth precise bore for consistent shot placement. Threaded with a 1/2x28 pattern the 3.71 barrel accepts a suppressor or muzzle device adding accessory compatibility that the factory barrel doesn t offer. This makes the Duty barrel a strong upgrade for shooters who want their compact carry pistol ready for suppressed training or use where legal. Built for hard-use concealed carry duty or training scenarios the barrel is designed to hold up under repeated firing without sacrificing reliability. The Faxon Duty barrel for Sig Sauer P365 is a rugged versatile upgrade for shooters who want more out of their ultra-compact pistol.
